In game, City scores broadcast (8)
I believe the answer is:
lacrosse
'in game' is the definition.
(I've seen this before)
'city scores broadcast' is the wordplay.
'city' becomes 'LA' (Los Angeles).
'broadcast' indicates anagramming the letters (letters scattered or cast around).
'scores' anagrammed gives 'crosse'.
'la'+'crosse'='LACROSSE'
(Other definitions for lacrosse that I've seen before include "Sport played with sticks" , "Score's uncertain after the Spanish" , "Ball game using netted stick" , "Like thirteen of the other clues in the French" , "Game played with a netted stick" .)
